Characteristics
HIFULL HB-151D is hydrophobic fumed silica which is produced by HL-150 after chemical post-treatment with dichlorodimethylsilane.（DDS-Treated）
Applications
Organic silicone rubber and sealants ( HTV, RTV);
Paints, Coatings & Toner;
Adhesives;
Cosmetics
Properties & Functions
※ Perform good reinforce, thickening and thixotropic properties in RTV & other adhesive products, can improve storage stability for organic silicone sealants;
※ Uses as rheology control agent in (composite) liquid system;
※ Anti-sagging, anti-corrosion in coatings, and improve stability of pigment;
※ Improve hydrophobic and rheological performance in offset printing ink;
※ Promote and keep free flow and anti-caking properties for powde
